Clause 231 (war guilt clause) could be argued to be an appropriate response to the cost and damage caused by German troops during the war.
The German cabinet in Berlin and the delegation in Paris were not permitted to negotiate the terms of the treaty for good reason; they had not accepted that the war was lost, and therefore could not be reliably allowed to negotiate the terms of a peace treaty.
The financial sections of the treaty are often the most maligned; they do demand £6.6bn from an ailing, defeated nation after all.
Overall, I believe that the Treaty of Versailles was an appropriate response to the damage caused by Germany during the Great War, and any damage to her people or financial sector is directly due to incompetence in the biased politics and frsnkly idiotic economic policies of the newly formed Weimar Republic and their desires to blame third parties for the economic issues caused by their own ineptitude.
